Application here: LISA Sprint
With more than 250 detected events, the LIGO-Virgo-KAGRA network has successfully concluded on November 18, 2025, the third part of the O4 observing run (O4c). An intense activity to analyze the collected data is ongoing, and in the meantime plans for upgrades toward O5 are prepared, to further increase the number of detected coalescences and with the aim of possibly detect new classes of gravitational wave emitters.
At the same time, the preparatory work for third generation ground-based interferometers Einstein Telescope and Cosmic Explorer is in full swing, with many R&D activities going on, new laboratories coming online and new concepts being elaborated, while the quality of the candidate sites are assessed. Lots of activities are also surrounding the preparation for the LISA mission, expected to probe a completely different band of the gravitational wave spectrum.
The gravitational wave community worldwide is growing, stimulated by the challenges of new detectors on Earth and in space. The Gravitational Wave Advanced Detector Workshop (GWADW) series is one of the main opportunities worldwide to present the work on detectors leaving, as is tradition, ample space for informal discussions.
The scientific programme will consist of plenary sessions only, with two poster sessions on Tuesday and Thursday afternoon. The daily work schedule will be concentrated in the morning and in the evening leaving room for informal discussions around lunch time.
GWADW 2026 will begin on Sunday, May 17th and finish on early morning of Saturday May 23rd.
The second generation of Gravitational wave (GW) detectors has been operating until recently at unprecedented sensitivity, providing observations of binary system coalescences, whose sources are neutron stars and black holes with masses ranging from one to one hundred solar masses.
The new (3rd) generation of gravitational detectors consists of two projects: Cosmic Explorer (CE) and Einstein Telescope (ET), supported respectively by US and European collaborations with Latin America (LATAM) scientists involved in both projects.
With the intent of covering the wide range of fundamental physics, astronomy and cosmology topics that can be addressed by the upcoming gravitational wave detectors, the goal of the workshop is to spur the contribution of LATAM researchers to the field, with dedicated sessions to all aspects of GW science including Cosmology, Fundamental gravity, Astrophysical populations, Multimessenger astronomy, Neutron stars, Dark matter, Data analysis and Instrument science.
This workshop will be preceded by the School on Astroparticle and Multi-messenger Astrophysics from June 15-26.
Organizers:
This is an exciting time in gravitational-wave astronomy! LIGO, Virgo, and KAGRA just finished their fourth observing run (O4). Data from the past three observing runs (O1, O2, and O3) and the beginning of O4 (O4a) are publicly available, and include over 200 detections of compact object mergers. And the list continues to grow as more confirmed detections are added.
After you enroll, you will receive a crash-course in gravitational-wave (GW) data analysis. By the end of this course, you should be able to:
This course includes lectures, software tutorials, quiz questions, and a data challenge. Complete the course and data challenge to receive a certificate.
The discovery of gravitational waves has opened an entirely new observational window on the Universe, and eccentric systems represent one of the most exciting frontiers. While most detected binaries to date are consistent with circular inspirals, there is mounting evidence that eccentricity may already be present in current events, with claims ranging from high-mass and low-mass black hole binaries to neutron star-black hole systems. Understanding, modeling, and interpreting eccentric sources is both timely and urgent. The workshop will bring together experts in theory, numerical relativity, data analysis, and astrophysics, as well as early-career researchers entering these fields. We aim to create a collaborative environment where participants can share results, exchange ideas, and identify the next key steps.
The core program of the workshop will take place on September 1st-4th, 2026 at the Corfu Summer Institute, which is located in Mon Repos park, a short walk from Corfu town. In addition, the conference center will also be open and available to us on September 5th-6th; attendees can take it as an opportunity to work in small groups while enjoying Corfu’s seaside, beaches, and great food.
The workshop will have a conference fee of 350 Euros (250 Euros for students) covering coffee breaks, lunches, welcome reception, conference dinner, and two excursions (hopefully on a boat). While we are unable to provide travel support, accommodation in Corfu in September is relatively inexpensive (but the beaches are still great!). The workshop will be in person without remote options.
GRAVITY2026: New Frontiers in Cosmology will be held on-site at the Institute for Basic Science (IBS) in Daejeon, Korea, from 27 April to 1 May, 2026. The aim of the workshop is to foster comprehensive and in-depth discussions on the rapidly expanding frontiers of gravitational physics. The program will cover a wide spectrum of topics central to cosmology, including gravitational waves, early- and late-time cosmology, and theories of modified gravity.

The workshop wants to bring together young researchers actively involved in the activities of the Observational Science Board (OSB), Instrumental Science Board (ISB) and Site Characterization Board (SCB) of the Einstein Telescope. Leaving plenty of room for discussions, it will be a great occasion to share research and ideas, start projects, learn about new topics, and build collaborations.
It does not matter whether you like cosmology or pulsars, individual sources or backgrounds, data analysis, cryogenics, quantum noise reduction, or novel sensing and control systems … if you are young and interested in ET science, this is the right place!
After an opening session on the broad activities of ET ISB, OSB and SCB, the workshop is organized as a series of parallel sessions between OSB and ISB, each featuring two talks by expert early career researcher, laying the ground on the topics of relevance for each division, followed by ample room for discussion.
As additional information for all the ET enthusiasts: there is another workshop, the Einstein Telescope Research Infrastructure: Challenges and Long-Term Sustainability workshop, to be held in Rome at Sapienza University on February 16–17.
Key dates
Registration open: October 22nd 2025

The purpose of the workshop is to bring together the leading institutes which are designing the vacuum and cryogenic systems of the Einstein Telescope (the third generation gravitational wave detector which is currently being designed in Europe) and European Big Science industries specialised in vacuum and cryogenic technologies, to discuss the challenges and opportunities ahead.
The event will be held in CERN, where the ET vacuum pilot sector is housed. The technical challenges and aimed companies are available in the following link, and the topics for industry contribution in this link.
Registration fee is 85 CHF and includes coffee breaks and an evening aperitif at CERN on 21 April. We encourage participants to book accommodation at the CERN hostel. The rate is 62 CHF for a single room with bathroom.
In recent years, the modelling of gravitational wave sources has become a cornerstone of theoretical and numerical relativity. Multiple communities—working with distinct formalisms such as Self-Force, Effective One Body (EOB), Effective Field Theory (EFT) and post-Newtonian approximations—have developed powerful tools to describe the two-body problem with increasing precision. Each of these approaches is advanced enough to come with its own set of language, notation, conceptual framework, and computational tools.
The workshop aims to bridge this gap and bring these communities closer together. This will be done by providing a mix of beginner friendly lectures, hands on coding sessions, plenary overviews together with state of the art research talks for each of the fields.
The workshop, to be hosted at the new German Centre for Astrophysics (DZA) in June 2026, builds on the highly successful Kavli-IAU Global Coordination Workshop series. This will bring together approximately 50 astronomers and astrophysicists from around the world to discuss the global considerations of time-domain astronomy and multimessenger astrophysics. The drivers for these areas over the next decade will be large, international projects which require prompt and coordinated follow-up of new astronomical discoveries that may disappear in just a few days, or even sooner.
The primary objectives of the workshop will be to 1) define and prioritise the outstanding scientific questions that require coordinated, multi-wavelength follow-up in this time period, and 2) produce a series of recommendations to be implemented by the astronomical community in order to achieve these scientific goals. It will bring together key representatives from the major projects involved in these areas as well as the broader astronomical community around the globe (including theorists, instrumentalists, and observers).
Recommendations will be translated into a report titled “An Updated RoadMap for Global Coordination in the Time-Domain and Multi-Messenger Eras”.
